Alias is not supported (in erDiagram)

Author: denilsonsaCreated Jun 16, 2026Updated Aug 29, 2026

According to the erDiagram documentation:

An alias can be added to an entity using square brackets. If provided, the alias will be showed in the diagram instead of the entity name.

erDiagram
    p[Person] {
        string firstName
        string lastName
    }
    a["Customer Account"] {
        string email
    }
    p ||--o| a : has
mermaid
erDiagram
    p[Person] {
        string firstName
        string lastName
    }
    a["Customer Account"] {
        string email
    }
    p ||--o| a : has

But it doesn't work in beautiful mermaid


Untested: if aliases are supported in other kinds of diagrams. I only looked at Entity-Relationship diagram.
